CHARLES L. KNEELAND, OF LANSING, MICHIGAN.

MILK-COOLER.

SPECIFICATION forming part of Letters Patent No. 499,840, dated J' une 20, 1893. Application tiled September 29, 1892'. 'Serial No. 447,306. (No model.)

To all whom it may concern.:

' Be it known that L'CHARLES L. KNEELAND, of Lansing, in the county of Ingham, in the State of Michigan, have invented new and useful Improvements in Creameries, of which the following, taken in connection with the accompanying drawings, is a full, clear, and

exact description.

My invention relates to creameries, in which the milk receptacles, cans or holders are set in a tank of cold water.

My object is to produce an improved creamery, comprising a tank having a transparent front, an ice chamber within the tank, communicating with the water chamber, a sloping bottom to the tank, glass milk cans permanently set into the tank bottom, and held apart and held down also, by means of elastic metallic bands, adj ustably7 connected together, and engaging with the walls, or tops, or both, of the several cans and supporting them laterally as Well as resisting any tendency of flotation of the cans when empty, and also operating to prevent any strain upon the neck of any can, tending either to break it, or loosen it so that it will not be'water tight; said cans being provided with faucets for drawing olf the milk and cream; and being also provided with a metallic, tubular draw-off pipe, removably inserted into the neck of each can, with a tight joint between them. p

My invention consists in the several novel features of construction and operation hereinafter described and which are specificr Vly set forth in the claims hereto annexed. It is constructed as follows, reference being had to the accompanying drawings, in which- Figure l, is a plan perspective of the creamery, with the outer doors and cover removed. Fig. 2, is a vertical transverse sectional elevation thereof. Fig. 3, is a vertical section of part of the tank, and a like section of the lower part of one can, and of the draw-off pipe. Fig. 4, is a sectional elevation of the lower part of the tank overiiow pipe.

A is the outer casing, usually provided with a cover, and doors, (not shown) for closing the top and front. The front is partly closed by a. glass a leaving an open space below the glass. A diaphragm comprising a slanting portion c a vertical portion cand a sloping portion c is connected tothe back and sides of the casing, in such manner as to make a Water-tight joint; cbeing the bottom of the ice chamber,l and c the bottom of the water chamber, while c is theback thereof. A grating of any desired size of mesh is supported across the front-of the ice chamber and operates topreventthe ice from coming into contact with the cans e The elevation of the bottom of the ice chamber also causes the cold watertherefrom, to first strike the upper half of the cans, and exert its cooling effect thereon rst, thereby cooling their top portions first, and which causes a circulation of the milk, producing a current and consequently will cause the cream to rise sooner and more perfectly. The cans eare of glass, of substantially the form of an inverted bottle, having at their lower ends a neck e and being open at the large or upper end. A tube lt liaring at its upper end is inserted through the neck, and packing material is interposed between its flaring end, and the glass. This tube also passes through a tubular abutment lt upon which the lower end of the can also rests, with a suitable packing between it and said can end. Anut 'm bearing against the bottom of the water tank, engaging with a thread upon said tube, operates to draw the tube tightly down into the neck of the can, to draw the lower end of the can down onto the abutment, and create water-tight joints all around; and this permanently mounts the can in position in the water tank. A faucet "rtis coupled onto the lower end of said tube, and by-it, after the milk is drawn off, the cream is drawn off, as into a pail set into the bottom of the casing. The water tank is provided with a suitable overflow pipe p and may also be provided with an ordinary faucet (not shown) with which to draw off all of the water therein. The tops of the cans are supported laterally by means of elastic metallic bands r the ends o f which are secured to the sides of the casing and which are drawn in between the cans by bolts r-, which draw the bands tightly around the cans. The bands are also provided with hooks r" which hook over the edges of the cans, and l :o to secure by Letters Patent, is

l. The combination with the casing, ofthe Water tank therein having a glass front, the ice chamber above the bottom of the tank and connected to said tank, and av grating be- I5 tween the ice and Water chambers.

2. The combination With the easing, the

Water tank therein, and the cans mounted upon the bottom of said tank, of the elastic bands secured to the Casin g and drawn around the cans, and provided with hooks engaging with the tops of the Cans.

3. The combination with the easing, the Water tank, and the Cans mounted upon the bottom ot'v said tank, of the ice chamber connected to the water tank, and the grating separating them.

.In witness whereof I have hereunto set my hand this 15th day of August, 1892.
